Abstract
PURPOSE To identify risk factors for clinical failure of uterine artery embolization (UAE) for postpartum hemorrhage (PPH), with particular attention to the uterine artery diameter. MATERIALS AND METHODS This retrospective study included 47 patients who underwent UAE for PPH between January 1, 2010, and January 31, 2021. Technical success was defined as the completion of embolization of the arteries thought to be the cause of the bleeding. Clinical success was defined as no recurrent bleeding or need for additional therapeutic interventions. Univariate and multivariate analyses were performed to examine the risk factors associated with clinical failure of UAE. RESULTS Of the 47 patients, 6 had recurrent bleeding. Of the 6 patients, 4 underwent hysterectomy, and 2 underwent repeat embolization. The clinical success rate was 87.2% (41/47), with no major adverse events such as uterine infarction or death. In univariate analysis, there were slight differences in multiparity (P = .115) and placental abruption (P = .128) and a significant difference in the findings of a narrow uterine artery on digital subtraction angiography (DSA) (P = .005). In multivariate analysis, only a narrow uterine artery on DSA was a significant factor (odds ratio, 18.5; 95% confidence interval, 2.5-134.8; P = .004). CONCLUSIONS A narrow uterine artery on DSA was a risk factor for clinically unsuccessful UAE for PPH. It may be prudent to conclude the procedure only after it is ensured that vasospasm has been relieved.

Abstract
OBJECTIVE Although fetal growth restriction (FGR) is associated with an increased risk of cesarean delivery during induced labor, there is limited evidence to guide labor management. This study aimed to investigate the prognosis of induced labor in pregnancies with suspected FGR and whether oxytocin discontinuation during the active phase of labor affects maternal and neonatal outcomes. STUDY DESIGN This retrospective cohort study investigated singleton pregnancies with vertex presentation and indications for labor induction owing to FGR after 34.0 weeks of gestation at Osaka University Hospital. From January 2010 to December 2013, women were conventionally managed, and oxytocin was continued until delivery unless there was an indication for discontinuation (conventional management group). From January 2013 to December 2020, oxytocin was routinely discontinued, or the dose was reduced at the beginning of the active phase of labor (oxytocin discontinuation group). RESULTS A total of 161 women (conventional management group, n = 74; oxytocin discontinuation group, n = 87) were included. After the active phase of induced labor, the total incidence of cesarean delivery was very low (3.1%), and the duration was short (173 ± 145 minutes). Oxytocin discontinuation was associated with lower cesarean delivery (1.1 vs. 5.4%; p = 0.12) and uterine tachysystole (9.8 vs. 23.0%; p = 0.08) rates and longer duration of the second stage of labor (mean: 56.5 ± 90 vs. 34.2 ± 45 minutes; p = 0.08) than conventional management; however, the difference was not significant. The other maternal and neonatal outcomes, including postpartum hemorrhage, did not also significantly differ between them. CONCLUSION After the active phase of induced labor for suspected FGR, the risk of cesarean delivery is low, and the high incidence of uterine tachysystole and rapid labor progression should be considered cautiously. Oxytocin can be safely discontinued during the active phase of labor in women undergoing labor induction for FGR without an increased risk of cesarean delivery or other unfavorable outcomes. KEY POINTS · The cesarean delivery rate was low after the active phase.. · The labor progress after the active phase was rapid.. · Oxytocin can be safely discontinued during the active phase..

Abstract
Abstract
Study question
To evaluate the effectiveness of chlormadinone acetate (CMA) for preventing premature LH surge in patients with normal ovarian reserve compared to cetrorelix.
Summary answer
In progestin-primed ovarian stimulation (PPOS) than GnRH antagonist (GnRH-ant), the incidence of premature LH surge was significantly lower, without significant difference in oocyte maturation rate.
What is known already
The GnRH-ant protocol is one of the conventional protocols which has some disadvantages including increased premature LH surge rate and cancelation rate. In recent years, the PPOS protocol has attracted attention as a new ovarian stimulation using progestin as an alternative to GnRH analog for suppressing a premature LH surge, however its efficacy is still controversial. In addition, many studies have investigated the reproductive outcomes of PPOS using medroxy-progesterone acetate or dydrogesterone; however, there are few reports of CMA, an oral progestin, which is inexpensive and widely used in Japan.
Study design, size, duration
This retrospective cohort study was performed in a reproduction center between March 2018 and October 2020 which included 977 Japanese patients with normal ovarian reserve undergoing PPOS with CMA (n = 299), or GnRH antagonist (GnRH-ant) with cetrorelix (n = 608) in their first IVF cycle at the reproduction center. In subgroup analysis, pregnancy outcomes after frozen embryo transfers (FET) between PPOS (n = 284) and GnRH-ant (n = 579) were also compared.
Participants/materials, setting, methods
The inclusion criteria were patients aged < 40 years and AMH ≧ 1.1 ng/mL, who underwent autologous oocyte retrieval in their first IVF cycle with freeze-all strategy. The primary outcome was the incidence of premature LH surge, the secondary outcomes was oocyte maturation rate. To reduce the impact of treatment bias and potential confounding factors, we conducted logistic regression models with inverse-probability-of-treatment weighting (IPTW).
Main results and the role of chance
After IPTW, baseline clinical data were well-balanced between the two groups, including age, AMH, BMI, the duration, type, and cause of infertility, antral follicle count, the history of recurrent spontaneous abortion, and previous IVF attempts. The premature LH surge rate was significantly lower with PPOS (3.1%) compared to GnRH-ant (20.1%) (odds ratio, 0.21; 95% confidence interval, 0.11–0.36). No significant differences were found in total gonadotropin dose (2400IU for PPOS vs 2400IU for GnRH-ant, p = 0.136), the number of oocyte retrieval (n = 15 vs n = 15, p = 0.484), oocyte maturation rate (78.8% vs 77.8%, p = 0.275), fertilization rate (73.0% vs 72.0%, p = 0.412), viable embryo rate per oocyte retrieval (40% vs 40%, p = 0.890), and good quality blastocyst rate (72.0% vs 69.6%, p = 0.092). However, the good quality day-3 embryo rate was significantly lower with PPOS (37.2% vs 49.1%, p < 0.05). There were no differences in the incidence of moderate-to-severe OHSS (0.3% vs 0.7%, p = 0.481). In FET cycles, the pregnancy outcomes, such as implantation rate (43.1 % vs 51.9 %, p = 0.013) and clinical pregnancy rate (46.5% vs 54.7%, p = 0.027) were significantly lower with PPOS, however, no significant differences were found in ongoing pregnancy rate (75.6% vs 80.5%, p = 0.325), and live birth rate (72.4% vs 79.5 %, p = 0.142).
Limitations, reasons for caution
This was a retrospective cohort study conducted in a single center. The participants in this study were limited to Japanese ethnicity. The results need to be validated across different centers and other ethnicities.
Wider implications of the findings
This is the first report assessing the reproductive outcomes on PPOS using CMA, widely used in Japan. The PPOS with CMA significantly suppressed the premature LH surge rate compared to GnRH-ant protocol, without decrease in oocyte maturation rate.

Abstract
OBJECTIVE We investigated the utility of combinational elastography with point shear wave elastography (pSWE) and real-time tissue elastography (RTE) for evaluating liver fibrosis in patients with liver injury. METHODS In this prospective single-institution study, patients scheduled for a liver biopsy to determine the presence of liver disease were enrolled. Liver fibrosis in each patient was evaluated using both shear wave velocity (Vs) shown by pSWE and the liver fibrosis index (LFI) shown by RTE, while a liver biopsy sample was obtained from the same area that was subjected to an elastography examination. Results of the latter were compared with those obtained in a histological examination. RESULTS Multivariate analysis showed that Vs and LFI were significantly correlated with the liver fibrosis stage in all of the enrolled patients. Sub-analysis findings compared patients with and without non-alcoholic fatty liver disease (NAFLD) and demonstrated that Vs was significantly correlated with the liver fibrosis stage in both groups, whereas LFI was correlated with that only in the non-NAFLD patients. However, a multivariate analysis demonstrated a significant correlation between steatosis grade and LFI in the NAFLD patients. CONCLUSIONS RTE is less useful than pSWE for assessing liver fibrosis in patients with NAFLD.

Abstract
Purpose To assess the clinical efficacy of personalized embryo transfer (pET) guided by a new endometrial receptivity test, ERPeakSM, in patients with recurrent implantation failure (RIF). Methods Recurrent implantation failure patients of all ages at two private Japanese clinics from April 2019 to June 2020 were retrospectively analyzed. The intervention group (n = 244) received pET in accordance with endometrial receptivity testing results and was compared to control group (n = 306) receiving standardized timing, non‐personalized embryo transfer (npET). In propensity score matching analysis, the clinical pregnancy rate (CPR) and live birth rate (LBR) were compared between groups, and a subanalysis of advanced maternal age (AMA) (≥38 years old) versus non‐AMA (<38 years old) patients was also conducted. Results The CPR and LBR of the pET group were significantly higher than those of the npET group (37.7% vs. 20.0%, adjusted OR: 2.64; 95%CI, 1.70–4.11, p < 0.001 and 29.9% vs. 9.7%, adjusted OR: 4.13; 95%CI, 2.40–7.13, p < 0.001, respectively). Furthermore, in the subanalyses, the CPR and LBR of the pET group were significantly higher than those of the npET group in both the AMA non‐AMA patients. Conclusions The new ERPeakSM endometrial receptivity test is a useful alternative diagnostic tool for poor‐prognosis patients, regardless of age.

Abstract
Preeclampsia is one of the most common as well as most severe complications of pregnancy, characterized by new-onset hypertension and proteinuria or other organ dysfunction. It predominantly occurs after 20 weeks of gestation. Very rarely, it can be triggered earlier in some specific situations. Here we report a case of fetal triploidy presenting as an extraordinarily early-onset preeclampsia. A healthy 36-year-old multiparous woman who had conceived naturally was hospitalized due to acute-onset severe hypertension accompanied by proteinuria at 18 weeks of gestation. Laboratory testing ruled out the presence of underlying maternal disease. Ultrasound findings, including multicystic large placenta and multiple fetal anomalies, strongly suggested fetal triploidy. Maternal ovaries showed hyperreactio luteinalis. The soluble fms-like tyrosine kinase-1/ placental growth factor (sFlt-1/PlGF) ratio was elevated, at 270. Medical abortion was carried out at 19 weeks of gestation; thereafter, her symptoms quickly resolved. Fetal triploidy was confirmed by genetic testing. We should be aware that fetal disorders including triploidy as well as pre-existing maternal diseases can provoke such very early-onset preeclampsia. Fetal ultrasound evaluation is critical and the sFlt-1/PlGF ratio is important for prompt diagnosis and management to prevent adverse maternal outcomes associated with atypical preeclampsia before 20 weeks of gestation. Fetal ultrasound and the sFlt-1/PlGF ratio are important to diagnose preeclampsia even before 20 weeks of gestation.

Abstract
A 65-year-old woman with a history of chronic hepatitis B was referred to our hospital for the examination of abdominal lymphadenopathy and diffuse lesions in the liver. Endoscopic ultrasound-guided fine-needle aspiration biopsy and liver biopsy were performed, and mucosa-associated lymphoid tissue (MALT) lymphoma was found in both. Based on the results of various images, a diagnosis of primary hepatic MALT lymphoma, Ann Arbor classification stage IV was reached at. Entecavir administration, H. pylori eradication therapy, and chemotherapy were performed, and remission was induced. The tumor condition remained unchanged after H. pylori eradication therapy and Entecavir administration. Subsequently, she became symptomatic, so chemotherapy was performed, leading to remission. We herein report a case of hepatic MALT lymphoma associated with chronic hepatitis B.

Abstract
Background The retained products of conception (RPOC) and related conditions (RPOC-ARC) are the main cause of secondary postpartum hemorrhage (sPPH), but there is no clear consensus for their management. The purpose of this study was to characterize those RPOC-ARC that require invasive treatment and those that could be managed more conservatively. Methods We retrospectively analyzed 96 cases of RPOC-ARC that occurred after miscarriage, abortion, or delivery at a gestational age between 12 and 42 completed weeks, that were managed within our institution from May 2015 to August 2020. We reviewed the associations between the occurrence of sPPH requiring invasive treatment with clinical factors such as the maternal background and the characteristics of the lesions. Results The range of gestational age at delivery in our study was 12–21 weeks in 61 cases, 22–36 in 5, and 37 or later in 30. Among them, nine cases required invasive procedures for treatment. The onset of sPPH was within one month of delivery in all but two cases, with a median of 24 days (range 9–47). We found significant differences between requirements for invasive versus non-invasive strategies according to gestational age at delivery, assisted reproductive technology (ART) pregnancy, amount of blood loss at delivery, and the long axis of the RPOC-ARC lesion (p = 0.028, p = 0.009, p = 0.004, and p = 0.002, respectively). Multivariate analysis showed that only the long axis of the lesion showed a significant difference (p = 0.029). The Receiver Operating Characteristic (ROC) curve for predicting the need for invasive strategies using the long axis of the lesion showed that with a cutoff of 4.4 cm, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) was 87.5, 90.0, 43.8, and 98.7%, respectively. Conclusion The long axis of the RPOC-ARC is a simple indicator for predicting which sPPH will require invasive procedures, which use is rare in cases with lesions less than 4.4 cm or those occurring after the first postpartum month. Conservative management should be considered in such cases.

Abstract
A 57-year-old female with a history of Cowden's disease was referred to our hospital because of black stool, loss of consciousness, and severe anemia. Upper and lower gastrointestinal endoscopy findings could not confirm the source of hemorrhage. Capsule endoscopy (CE) of the small intestine showed an active exudative hemorrhagic site near the ileum, although a definitive diagnosis was difficult. In a double balloon enteroscopy examination, it was difficult to observe the entire small intestine due to adhesions and the responsible lesion could not be confirmed, even when ink spots were applied to the deepest observation points through the mouth and anus. Hemostasis spontaneously occurred, and then anemia occurred again approximately 1 month later and a second CE examination was performed including passage of an ink stick through the oral side, which revealed an exudative elevated polyp with erosion and a white moss appearance in the ileum. Partial ileal resection was performed and pyogenic granuloma of the small intestine was the diagnosis. We report here a case of pyogenic granuloma of the small intestine associated with Cowden's disease.

Abstract
BACKGROUND Sigmoid volvulus is a common condition in elderly patients with elongated colons. Although endoscopic de-torsion is effective as the primary treatment of sigmoid volvulus, elective surgery is recommended because of the high risk of recurrence and high mortality rate. AIM The aim of this study was to determine the risk factors for the recurrence of sigmoid volvulus. METHODS Clinical records of patients treated at Shimane Prefectural Central Hospital were reviewed retrospectively. Among 41 sigmoid volvulus patients who were successfully treated by endoscopic de-torsion and followed up, 30 were observed over 1 year. Among the 30 patients, eight (26.7%) did not experience recurrence, while 22 (73.3%) did. Initial computed tomography (CT) findings indicating the sigmoid colon extending to the diaphragm or ventral to the liver were defined as "extension findings." Extension findings and sigmoid diameter were evaluated in relation to sigmoid volvulus recurrence. RESULTS Extension findings were significantly more frequent in the recurrent group (77.3%) than in the nonrecurrent group (25.0%) (P = 0.009). Distended sigmoid colon diameter was significantly larger in the recurrent group (11.7 ± 3.8 cm) than in the nonrecurrent group (7.1 ± 1.1 cm) (P = 0.044). Receiver operating characteristic curve analysis demonstrated that the performance threshold was greater than 8.9 cm. Kaplan-Meier analysis showed the significantly high sigmoid volvulus recurrence rate in the patients with extension findings and a distended sigmoid colon greater than 8.9 cm. CONCLUSIONS CT findings of a long and distended sigmoid colon in initial sigmoid volvulus are risk factors for the recurrence of sigmoid volvulus.

Abstract
Background A diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes. Methods This single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed. Results The study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04). Conclusions PEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.

Abstract
BACKGROUND The efficacy of preemptive analgesia in managing postoperative pain remains controversial. The aim of this study was to compare the efficacy of intravenous (IV) acetaminophen administered before or immediately after the surgical extraction of an impacted mandibular third molar. MATERIAL AND METHODS This prospective randomized clinical trial included 120 patients. The patients were assigned to one of three groups: the preoperative-treatment group (pre-group), which received 1000 mg of IV acetaminophen 20 min before surgery; the postoperative-treatment group (post-group), which received 1000 mg of IV acetaminophen after surgery; the no-treatment group (control-group), which did not receive any analgesic. Rescue analgesic (60 mg loxoprofen) was issued to each patient, with instructions on self-administration if needed. For the rescue medication usage, the time of first loxoprofen usage and the total amount of loxoprofen consumption were obtained for a 17-hour period after surgery. We measured pain using the visual analogue scale at 1 hour and at 2, 3, 4, 5, and 15 hours after surgery. RESULTS There was no significant difference in pain level among the three groups at any time interval. However, the pre-group demonstrated significantly lower rescue analgesic consumption and longer time until initial administration. CONCLUSIONS Administration of IV acetaminophen before third molar surgery provides more effective pain control than postoperative administration and no treatment.

Understanding the structure-property relationship of glass material is still challenging due to a lack of periodicity in disordered materials. Here, we report the properties and atomic structure of vanadium phosphate glasses characterized by reverse Monte Carlo modelling based on neutron/synchrotron X-ray diffraction and EXAFS data, supplemented by Raman and NMR spectroscopy. In vanadium-rich glass, the water durability, thermal stability and hardness improve as the amount of P2O5 increases, and the network former of the glass changes from VOx polyhedra to the interplay between VOx polyhedra and PO4 tetrahedra. We find for the first time that the coordination number of oxygen atoms around a V4+ is four, which is an unusually small coordination number, and plays an important role for water durability, thermal stability and hardness. Furthermore, we show that the similarity between glass and crystal beyond the nearest neighbour distance is important for glass properties. These results demonstrate that controlling the oxygen coordination and valence of the network-forming cation is necessary for designing the properties of glass.

Abstract
The chiral crystal is characterized by a lack of mirror symmetry and inversion center, resulting in the inequivalent right- and left-handed structures. In the noncentrosymmetric crystal structure, the spin and momentum of electrons are expected to be locked in the reciprocal space with the help of the spin-orbit interaction. To reveal the spin textures of chiral crystals, we investigate the spin and electronic structure in a p-type semiconductor, elemental tellurium, with the simplest chiral structure by using spin- and angle-resolved photoemission spectroscopy. Our data demonstrate that the highest valence band crossing the Fermi level has a spin component parallel to the electron momentum around the Brillouin zone corners. Significantly, we have also confirmed that the spin polarization is reversed in the crystal with the opposite chirality. The results indicate that the spin textures of the right- and left-handed chiral crystals are hedgehoglike, leading to unconventional magnetoelectric effects and nonreciprocal phenomena.

Abstract
BACKGROUND Uterine artery embolization (UAE) is used to treat severe postpartum hemorrhage (PPH). According to a few studies, UAE for PPH was associated with preterm birth, fetal growth restriction (FGR), and placenta accreta spectrum (PAS) in subsequent pregnancies. These previous studies, however, lacked controls, and to the best of our knowledge, no systematic literature reviews have been conducted thus far. We report the results of our retrospective case-control study of pregnancies after UAE at a single center and include a literature review to evaluate the risk of PAS in pregnancies after UAE. METHODS We retrospectively reviewed data from deliveries at our hospital between January 2012 and October 2017. We divided the delivery data into cases with previous UAEs performed for PPH (the post-UAE group) and those without UAEs (the non-UAE group, which included women without previous PPH). We defined PAS as cases in which hysterectomy was performed and pathological examination confirmed the diagnosis. Results are presented as odds ratios (ORs) with 95% confidence intervals (95% CIs). RESULTS We used data from 3155 patients in this study, of whom 16 patients had undergone UAE (post-UAE group) and 3139 had not (non-UAE group). We found no differences between the groups in terms of frequency of preterm births (12.5% versus 14.2%, respectively; OR, 0.863; 95% CI, 0.218 to 3.414; P = 0.84) or FGR (6.2% versus 10.0%, respectively; OR, 0.602; 95% CI, 0.104 to 3.584; P = 0.61). However, cases of PAS were significantly more common in the post-UAE group (37.5%) than in the non-UAE group (1.2%; OR, 50.303; 95% CI, 17.38 to 145.592; P < 0.01). CONCLUSION Our results suggest that previous UAE is a significant risk factor for PAS.

Abstract
AIM This study aimed at evaluating the additional anti-tumor effects of exogenous rVEGFR1 (sFlt1) on conventional chemotherapy in ovarian cancer cell lines. METHODS We utilized cells from two ovarian cancer cell lines, SKOV3 and HeyA8, and treated them with a combination of rVEGFR1 (sFlt1) and carboplatin as well as rVEGFR1 (sFlt1) alone. First, we evaluated cell survival after treatment by using cell counting and MTS assays. Next, we performed Ki67 staining for evaluating the inhibitory effects of the treatment on cell proliferation, and a lactate dehydrogenase (LDH) assay for evaluating cytotoxicity. Finally, to determine whether MAP kinase signaling is involved in this process, we performed western blot analysis of extracellular signal-regulated kinase (ERK), phospho-ERK, c-jun n-terminal kinase (JNK) and phospho-JNK. RESULTS The cytotoxic and growth-restriction effects were more pronounced in the group co-administered with rVEGFR1 (sFlt1) and carboplatin than in cells treated with either rVEGFR1 (sFlt1) or carboplatin alone. Quantitative analysis of Ki67-positive cells also showed a decreased proportion of Ki67-positive cells in SKOV3 cells treated with a combination of exogeneous rVEGFR1 (sFlt1) and carboplatin compared to that in cells treated with either rVEGFR1 (sFlt1) or carboplatin alone. In the LDH assay, we also found significantly enhanced cell toxicity from the combination therapy. Finally, western blotting analysis showed that the MAPK signaling pathway was not affected by sFlt1 treatment. CONCLUSION This study confirmed the additive effects of rVEGFR1 (sFlt1) combined with conventional chemotherapy for ovarian cancer growth in in vitro assays, thus suggesting the combination of rVEGFR1 (sFlt1) and carboplatin as a potential novel therapeutic option for ovarian cancer.

Abstract
Background This study aimed to identify and review associations between the types of sutures used for uterine compression suture (UCS) and its outcomes in postpartum hemorrhage. Methods An electronic search using PubMed and Scopus databases was performed. We included the English articles reported from January 1, 1997, to May 31, 2017, using search words or terms regarding the types of suture and needle used for UCSs. We only included studies describing the sutures in the systematic review. Results We found 196 studies and included 76 (38.8%) in our analysis. We collected data on maternal outcomes for 924 patients and categorized them. Of the 76 studies, suture sizes 0, 1, and 2 were used in 6, 44, and 32 articles, respectively (some studies used multiple sutures). Of the 45 studies mentioning the needles, curved and straight needles were used in 35 and 10, respectively. The results of our review revealed that about 80% of previous articles used Catgut and Polyglactin 910 sutures. Because no studies that compared the efficacy of different size of sutures were identified, we investigated the differences using the cases reported in previous studies mentioned above. In the first analysis, we compared the uterine preservation rate between size 1 and size 2 sutures. We found no significant difference in uterine preservation rate (92.8%: size 1 vs. 94.2%: size 2, p > 0.05) but found significant difference in transfusion rate (62.4% vs. 79.1%, p < 0.01). With the hypothesis that non-transfusion cases were less severe, we excluded these cases from second analysis. Although our second analysis of only Catgut or Polyglactin showed strong selection bias, we observed that uterine preservation rate was significantly higher in cases with size 2 suture than in those with size 1 suture (86.9% vs. 93.5%, p = 0.033). Conclusions Our systematic review showed that approximately 80% of cases were treated by Catgut and Polyglactin 910. Due to the heterogeneity of cases included in this review, it is difficult to estimate which suture is better for UCSs. More robust studies are necessary to enable the identification of the superior suture for performing UCSs.

Abstract
Mid-esophageal diverticulum is a rare disease, formed by the traction caused by inflamed bronchial lymph nodes or by pulsion induced by motility disorder. We herein report a case of mid-esophageal diverticular bleeding in a patient with kyphosis who was taking an anti-platelet drug. She was successfully treated with endoscopic hemostasis. An 80-year-old woman presented to our emergency department with hematemesis. She had kyphosis and was taking dipyridamole for her chest pain. Emergent upper endoscopy revealed bleeding from a mid-esophageal diverticulum; hemostasis was achieved via clipping. Mid-esophageal diverticula can cause upper gastrointestinal bleeding. An endoscopic examination and hemostasis are effective treatments.

Abstract
Fractures are medical conditions that compromise the athletic potential of horses and/or the safety of jockeys. Therefore, the reduction of fracture risk is an important horse and human welfare issue. The present study used molecular genetic approaches to determine the effect of genetic risk for fracture at four candidate SNPs spanning the myostatin (MSTN) gene on horse chromosome 18. Among the 3706 Japanese Thoroughbred racehorses, 1089 (29.4%) had experienced fractures in their athletic life, indicating the common occurrence of this injury in Thoroughbreds. In the case/control association study, fractures of the carpus (carpal bones and distal radius) were statistically associated with g.65809482T/C (P = 1.17 x 10-8 ), g.65868604G/T (P = 2.66 x 10-9 ), and g.66493737C/T (P = 6.41 x 10-8 ). In the retrospective cohort study using 1710 racehorses born in 2000, the relative risk (RR) was highest for male horses at g.65868604G/T, based on the dominant allele risk model (RR = 2.251, 95% confidence interval 1.407-3.604, P = 0.00041), and for female horses at g.65868604G/T, based on the recessive allele risk model (RR = 2.313, 95% confidence interval 1.380-3.877, P = 0.00163). Considering the association of these SNPs with racing performance traits such as speed, these genotypes may affect the occurrence of carpus fractures in Japanese Thoroughbred racehorses as a consequence of the non-genetic influence of the genotype on the distance and/or intensity of racing and training. The genetic information presented here may contribute to the development of strategic training programs and racing plans for racehorses that improve their health and welfare.

Abstract
Abstract
Background
Recently, some studies have highlighted proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors produce incremental low-density lipoprotein cholesterol (LDL-C) lowering effect. However, it is unknown whether the lipid composition of plaque changes is associated with serum LDL-C reduction due to PCSK9 inhibitors administration.
Purpose
The purpose of this study was to determine the effects of PCSK9 inhibitor (PCSK9i) on coronary plaque component in patients with a history of coronary artery disease (CAD) assessed by near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS).
Methods
A total of 67 non-culprit coronary segments were identified in 34 patients. These lesions were analyzed utilizing NIRS-IVUS at baseline and follow-up coronary angiography (CAG). The subjects were divided into two groups according to lipid-lowering treatment; administration of PCSK9i group (PCSK9i: 19 segments, 9 patients) and traditional statin treatment group (Control: 48 segments, 25 patients). The change of lipid-rich plaque distribution between baseline and follow-up NIRS-IVUS was defined as the change of maximal lipid core burden index (LCBI) score for each of the 4-mm longitudinal segments (maxLCBI4mm).
Results
Mean duration from baseline to follow-up CAG was 239.4±52.4 days in the PCSK9i group and 341.0±84.1 days in the Control group (p<0.001). Despite the higher total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the PCSK9i group at baseline (206.6±40.9 mg/dl vs. 168.5±37.1 mg/dl, 131.5±35.4 mg/dl vs. 100.0±29.5 mg/dl; respectively, p<0.001 for both), the PCSK9i group was significantly lower TC and LDL-C at the follow-up (111.5±23.5 mg/dl vs. 157.4±27.8 mg/dl, 40.8±15.7 mg/dl vs. 86.2±19.6 mg/dl; respectively, p<0.001 for both). Furthermore, the PCSK9i group induced greater regression of maxLCBI4mm than that of Control group (99.6±156.6 vs. 27.9±118.0, p=0.046) (Figure).
Figure 1
Conclusion
Compared with traditional statin therapy, PCSK9i treatment resulted in a greater decrease in lipid component in non-culprit coronary plaques. Therefore, PCSK9i may be useful option in preventing from adverse coronary events for the patients with CAD.

Abstract
As a rarely recognized foreign body in the upper gastrointestinal tract, rice cake frequently requires endoscopic removal. We herein report six patients with characteristic sonography, computed tomography (CT), spectroscopy, endoscopy, and histological findings. A review of all published cases, including ours, revealed that retained rice cake in the stomach typically shows the following: abdominal pain (93.3%), mucosal injury (93.3%) with bleeding (42.9%); high-density (120-206 Hounsfield units) CT findings; and indication for endoscopy (80%). In the esophagus, hot, toasted rice cake causes thermal injury. Primary physicians should be aware of this popular-food-induced, but rare, disorder.

Abstract
AIM In this study, we aimed to investigate whether there was a significant prognostic difference between single and multiple cervical dilations when inducing second-trimester abortion. METHODS We conducted a retrospective review of 238 pregnant women who underwent termination of pregnancy at 12-21 weeks of gestation at Osaka University Hospital in Osaka, Japan, between January 2010 and May 2018. Termination of pregnancy was performed by vaginal administration of 1 mg gemeprost every 3 h for up to five doses per day after uterine cervical dilation using lamicel. RESULTS The women were categorized into two groups: 191 women had a delivery time of <24 h, whereas 47 had delivery times >24 h. Contrasting the groups, there were significant differences with regard to numbers of primiparas (88 [46.1%] and 32 [68.1%], respectively) and lamicel exchanges ± SD (1.9 ± 0.67 for <24 h and 2.4 ± 0.87 for >24 h, respectively). Additionally, we compared the prognosis of primiparas that received just a single lamicel with that of primiparas that had ≥2 exchanged, but no significant differences were noted in the number of patients with a delivery time of >24 h and the number of used gemeprost. CONCLUSION Primipara is a risk factor for delayed delivery time of induced abortion. However, increasing the number of exchanged lamicel did not significantly reduce the delivery time; therefore, it should be performed as minimally as possible.

Abstract
Intravascular large B-cell lymphoma (IVLBCL) frequently involves the hepatobiliary system, but its clinical course and pathophysiology are still not fully known. We herein describe a case of IVLBCL mimicking acute hepatobiliary infection. An 85-year-old woman was admitted because of fever and epigastric pain, and she was diagnosed to have acute acalculous cholecystitis based on gallbladder wall thickening with fluid collection. The gallbladder swelling regressed within several days, and areas of intrahepatic hypoperfusion appeared. Inflammation continued despite treatment with antibiotics, and she died within 21 days. An autopsy examination revealed IVLBCL. IVLBCL can present as acute cholecystitis with an improvement in the imaging findings and the presence of a subsequent liver mass.

Abstract
Background and study aims A 72-year-old man with complete situs inversus presented with early gastric cancer on the lesser curvature wall of the antrum of the stomach. Endoscopic submucosal dissection (ESD) was selected as a treatment. When the patient was positioned in the left decubitus position, the lesion was hidden by blood and gastric fluid because it was located on the gravitational side. Therefore, we decided to perform ESD with the patient in the right lateral decubitus position and use an inverted overtube, which provided a good endoscopic view without the need to rearrange the endoscopist, assistants, or endoscopic system. ESD was safe and feasible using the inverted overtube.

Abstract
Abstract
Background
In the eighth edition of the AJCC cancer staging classification, the T system for distal cholangiocarcinoma (DCC) has been revised from a layer-based to a depth-based approach. The aim of this study was to propose an optimal T classification using a measured depth in resectable DCC.
Methods
Patients who underwent pancreatoduodenectomy for DCC at 32 hospitals between 2001 and 2010 were included. The distance between the level of the naive bile duct and the deepest cancer cells was measured as depth of invasion (DOI). Invasive cancer foci were measured as invasive tumour thickness (ITT). Log rank χ2 scores were used to determine the cut-off points, and concordance index (C-index) to assess the survival discrimination of each T system.
Results
Among 404 patients, DOI was measurable in 182 (45·0 per cent) and ITT was measurable in all patients, with median values of 2·3 and 5·6 mm respectively. ITT showed a positive correlation with DOI (rs = 0·854, P < 0·001), and the cut-off points for prognosis were 1, 5 and 10 mm. Median survival time was shorter with increased ITT: 12·4 years for ITT below 1 mm, 5·2 years for ITT at least 1 mm but less than 5 mm, 3·0 years for ITT at least 5 mm but less than 10 mm, and 1·5 years for ITT 10 mm or more (P < 0·001). This classification exhibited more favourable prognostic discrimination than the T systems of the seventh and eighth editions of the AJCC (C-index 0·646, 0·622 and 0·624 respectively).
Conclusion
ITT is an accurate approach for depth assessment in DCC. The four-tier ITT classification with cut-off points of 1, 5 and 10 mm seems to be a better T system than those in the seventh and eighth editions of the AJCC classification.

Abstract
Fitz-Hugh-Curtis syndrome (FHCS) is defined as inflammation on the surface of the liver following sexually transmitted chlamydia infection. We successfully observed the microvascular structure of the inflamed portion between the abdominal wall and surface of the liver in an elderly patient with FHCS using a superb microvascular imaging (SMI) system, a new technology developed for observing minute vascular flow. An 80-year-old Japanese female with right dorsal to lateral abdominal pain and fever came to our hospital. Anti-chlamydia antibodies were positive. SMI revealed signals suggesting small vessels passing from the liver surface to the hypoechoic space.

Abstract
Objective We investigated the possible factors for predicting the future progression to hepatocellular carcinoma (HCC) from hypovascular nodules detected in the hepatobiliary phase of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-MRI). Methods A total of 91 hypovascular nodules detected by Gd-EOB-DTPA-MRI in 28 patients without any past history of treatment for HCC were retrospectively examined. The nodules were categorized into those with and without HCC progression, then comparisons were made to identify any factors possibly related to a progression to HCC in each case. In addition, we performed a receiver operating characteristics (ROC) analysis to determine the cut-off value for the initial nodule size for predicting HCC progression within 12 months. Results The observation period of the 28 patients was 1,172.6±95.6 (mean±standard error) days. The number of hypovascular nodules that changed to hypervascular ones was 15 (16.5%), and the cumulative incidence of hypervascular transformation was 7.1% at 12 months and 12.7% at 24 months. Of all 91 hypovascular nodules, 33 in 18 patients were diagnosed as HCC based on hypervascular transformation and/or size enlargement, while the remaining 58 did not progress to HCC. There was no significant difference regarding the background characteristics between the HCC progressed and non-progressed groups according to a multivariate analysis, or between the patients who had nodules that progressed to HCC and those with nodules that did not progress to HCC. Regarding HCC progression at 12 months, the area under the ROC (AUROC) had a level of 0.745 and showed that an initial nodule cut-off size of 9.5 mm (sensitivity, 57.9%; specificity, 87.3%) was predictive. Conclusion In patients without a past HCC treatment history, it is difficult to determine whether hypovascular nodules have a high risk of progression to HCC based on background factors alone.

Abstract
Gastritis cystica polyposa is a polypoid lesion that arises from the gastric mucosa at the gastrojejunal anastomotic site and is characterized by cystic dilation of the gastric glands. A 78-year-old man who underwent distal gastrectomy for a gastric ulcer with Billroth II reconstruction approximately 40 years previously, exhibited a gastritis cystica polyposa at the anastomotic site. Ulceration was observed on an annual endoscopic examination. Endoscopic ultrasonography revealed a submucosal hypoechoic mass with multiple cystic lesions. Gastrectomy was performed and histological examination revealed a large-cell neuroendocrine carcinoma with cystic dilation of the gastric glands. Here, we report the first case of a large-cell neuroendocrine carcinoma arising from a gastritis cystica polyposa. Endoscopic ultrasonography was effective at diagnosing a submucosal hypoechoic mass with cystic dilation of the gastric glands.

Abstract
The efficacy of repeated lusutrombopag administration for thrombocytopenia in patients with chronic liver disease who undergo two or more planned invasive procedures is unknown. We herein report our findings regarding the effects of repeated lusutrombopag administration given to avoid platelet transfusion in a patient with chronic liver disease and thrombocytopenia. The platelet count showed a positive response to lusutrombopag treatment prior to the initial invasive procedure to treat a hepatoma, so platelet transfusion was not necessary. In conclusion, lusutrombopag may be a useful drug for patients with thrombocytopenia to avoid platelet transfusion in those undergoing two or more planned invasive procedures.

Abstract
We report the case of a 71-year-old Japanese man with squamous cell carcinoma arising from lupus vulgaris on the face, >60 years after the appearance of the lupus vulgaris. The red plaque on the patient's face had been diagnosed as a hemangioma or rosacea at several hospitals, although he had had lung tuberculosis at the age of 4 and his father died from lung tuberculosis at 38 years of age. Although lupus vulgaris was the most frequent clinical form of true skin tuberculosis until the 1960s, it has become rare since then. Malignant tumors are known to occur in individuals with lupus vulgaris, with a reported rate of 0.5-10.5%. In light of Japan's "graying society," tuberculosis is still an important disorder, and clinicians must remain aware of cutaneous tuberculosis.

Abstract
Background and study aims Recurrence of common bile duct stones (CBDS) in patients treated with endoscopic sphincterotomy (ES) can lead to deterioration in their quality of life. Although the pathology and related factors are unclear, we speculated that proton pump inhibiter (PPI) administration increases the risk of CBDS recurrence by altering the bacterial mixture in the bile duct. Patients and methods The primary endpoint of this retrospective study was recurrence-free period. Several independent variables considered to have a relationship with CBDS recurrence including PPI use were analyzed using a COX proportional hazard model, with potential risk factors then evaluated by propensity score matching analysis. Results A total of 219 patients were analyzed, with CBDS recurrence found in 44. Analysis of variables using a COX proportional hazard model demonstrated that use of PPIs and ursodeoxycholic acid (UDCA), as well as the presence of periampullary diverticula (PD) each had a hazard ratio (HR) value greater than 1 (HR 2.2, P = 0.007; HR 2.0, P = 0.02; HR 1.9, P = 0.07; respectively). Furthermore, propensity score matching analysis revealed that the mean recurrence-free period in the oral PPI cohort was significantly shorter as compared with the non-PPI cohort (1613 vs. 2587 days, P = 0.014). In contrast, neither UDCA administration nor PD presence was found to be a significant factor in that analysis (1557 vs. 1654 days, P = 0.508; 1169 vs. 2011 days, P = 0.121; respectively). Conclusion Our results showed that oral PPI administration is a risk factor for CBDS recurrence in patients who undergo ES.
